WebThe hydrolysis of a peptide bond is helped along by two common means, and those two means are with the help of strong acids or with proteolytic enzymes. So when we use strong acids, we call this acid hydrolysis. And acid hydrolysis, when combined with heat, is a nonspecific way of cleaving peptide bonds. WebDec 27, 2024 · Mechanism of Trypsin. Since the active site is exactly the same in trypsin and chymotrypsin, the mechanism is exactly the same for both as well. There are four steps in this mechanism: Step 1 ... In vivo, chymotrypsin is a proteolytic enzyme (serine protease) acting in the digestive systems of many organisms. It facilitates the cleavage of peptide bonds by a hydrolysis reaction, which despite being thermodynamically favorable, occurs extremely slowly in the absence of a catalyst.
